Re: Goodman GMNT060-3B
Transformers don't click. Unless they're on fire. But even then it's more of a pop.
9 hours is a long time to come up empty handed. What's the serial number on the Goodman furnace?

Re: Goodman GMNT060-3B
You have 7 safeties wired between the w terminal on the thermostat and the gas valve. I would guess the inducer pressure switch is the most likely offender. Disconnect the switch and blow out the tubing connected to the switch and make sure they are all clean. Some of these safeties may be auto reset or manual reset.
You can also start the furnace and jumper the two switch wire to see if the furnace will continue to run.

Re: Moving column cast iron radiator valve to outlet
The valve will function with reverse flow as you propose — just not at reliably. However, I have to ask… is this system piped all parallel (home run) flow to a manifold? Otherwise… you may have some unpleasant surprises.
Re: Goodman GMNT060-3B
Check and make sure that all ground wires in the furnace and all the way back to the electric panel have good connections. The ignition system uses the ground with micro voltage passing through it to prove the flame.
Also: has the flame rod been replaced?

Re: No 1 Ideal Sectional Boiler from American Radiator Company on house built in 1926
The boiler looks good. The field MG1 is double action vent regulator designed to protect against downdrafts. As long as the face is plumb and the hinge, level, it can be adjusted to maintain the proper draft over fire. There should be a test hole to measure draft on the flue pipe between the regulator and the boiler breach. However the best place for a hole is 12" from breach, elbows and regulator which cannot be here so it has to go in the middle between both. Draft over fire from a warm flue should be about -.02" WC. and at the flue breach about -.04" WC. In these old boilers overfire may be hard to get to -.02" as the boilers internal path is fairly wide open. But if it is not making any soot, the combustion should be correct. The water stain on the right may be nothing or a sign of age and leaks on a section or two. Otherwise, it is tough to let the old girl go. Remember the longer it lives, the cheaper per day its life cycle cost is. So if you put a new boiler in and all you save is 10-20% over the fuel bill, you might consider which is cheaper. Divide projected fuel cost savings into the price of replacement and factor where you will be. If I pay $7,000.00, more or less to save 20% off of $1,600.00, 370.00/ year aver price over say 6 years it may take a 17 years to make up the difference. But if the boiler fails, its times to renew. Just remember there are a lot less parts to fail on this boiler than some of the new ones, which need more maintenance. Some new Weil Mclain boilers recommend service every year which costs at least 400.00 or more.
Water level looks ok. There are two levels to watch. 1 is when it is off and all water is drained down. The other is when on and there is water in the system above. The key to water is it clean, does it seem fairly steady when on. Water level if manual needs this reference, if automatic it needs to done right to meet the system demands. One thing I have always had to deal with is if the burner shuts of by low water cutoff when needing to fill. It changes the action. I always liked a fill control to feed water at a rate and time to keep the burner running as long as the stat calls for it. But it depends on boiler design. Of course most of my work is in a cold house. Best way to test is if the house has been maintaining comfort.
My previous comment on another field control in another pic did not show me if it was dual acting.

Re: Weil McLain EG50 no power after a pop
I have a question about the thermostat you are using.
Did you happen to try to connect a Smart Thermostat that requires a C terminal along with the R and the W terminal on the thermostat? That may be the reason for your POP
Re: Weil McLain EG50 no power after a pop
Get a whole new fan center control. The pop you heard was likely the transformer. And the base of the terminal board is lifted off on the right side. Shut the power off, stick your head in there and give it a sniff. Probably pretty rank. Add an in-line fuse like Ed said, because it could be it was the transformers time to pass, or there could be a short somewhere.

Re: Weil McLain EG50 no power after a pop
That relay is for operating a fan when used on a old gas furnace that has been upgraded with a central AC or with a boiler that uses a circulator to move water around the system. Since this is a steam boiler, you do not need the relay since there is no Fan or Circulator. That is why Weil McLain sells that without the relay for steam boilers 510-312-166 and with the relay for water boilers 510-312-167. I used to be the Weil McLain part guy at the supply house I worked for. So any WM part for boilers from 1996 and before are memorized. The Honeywell R8285A1048 would be a lower price replacement for that part with the relay included. and the AT72D1006 is even cheaper but does not have the G, Y, and W wire connectors on it. You need to use wire nuts in lieu of screw connectors.
Re: Quick question regarding direct-vent water heater install
Hi, Depending on the diameters of the inner and outer pipes, you may be able to leave the wall penetration in place and just attach the new heater after the 90, before it goes into the wall… unless that violates the manufacturer's sensibilities. 🤨
